CVE-2016-5284 (opens in a new tab)How to fix?
Upgrade Oracle:7 firefox to version 0:45.4.0-1.0.1.el7_2 or higher.
This issue was patched in ELSA-2016-1912.
NVD Description
Note: Versions mentioned in the description apply only to the upstream firefox package and not the firefox package as distributed by Oracle.
See How to fix? for Oracle:7 relevant fixed versions and status.
Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 rely on unintended expiration dates for Preloaded Public Key Pinning, which allows man-in-the-middle attackers to spoof add-on updates by leveraging possession of an X.509 server certificate for addons.mozilla.org signed by an arbitrary built-in Certification Authority.
